Two knights and a pawn too many

by Karsten Müller
5/21/2019 – It is strange but two knights alone cannot force checkmate. However, things are different when the defending side still has a pawn at or behind the so-called Troitzky-line. It also depends on where the defending king is placed. Karsten Mueller explores some of the secrets of this unusual endgame.

Mating with the knights

If White manages to block the enemy pawn when the pawn is standing on the squares a4-b6-c5-d4-e4-f5-g6-h4 or further back (the so-called Troitzky-line) White always wins — although in some cases only by ignoring the 50-move-rule. However, if the pawn is beyond the Troitzky-line — as in our example — things are less clear. But Black loses if his king happens to be on the wrong squares. These losing zones are close to the corner of the board, in this case h8 and a1.

Michel de Saboulin points out:
"You probably know that this ending was also annotated by Adhiban Baskaran in New In Chess Magazine 2018/8 (p. 57), who also pointed that the black King went to the wrong direction. I sent a mail to NIC editors, showing that the same position had already occurred, with the same error, in another game (Pena Gomez – Xoel Perez, Ourense 2007). My remark has been published in New In Chess Magazine 2019/1 (readers’ forum, p. 11)."
